What is the key to the quality of diapers?

1. Look at the product introduction

The material of the product, the exquisite use of materials, and the handling of details are closely related to the product. Knowing the material and materials of the product, it is convenient for us to check the information and confirm whether it is true.


2. Resilience

If you have a moving baby at home, you must pay special attention to it, as the baby's disorderly movement may make the diaper not close to the body and cause side leakage. A diaper with good elasticity can fit better. Moms can repeatedly pull the Velcro on the waist of the diaper to feel the elasticity of the Velcro.


3. Softness

Mothers can feel the softness of diapers. The elasticity of softness and pure softness are two concepts. Because the design of the surface layer and core of the diaper is different, mothers can feel it first on their arms.


4. Breathability

Nothing is more important than breathability in summer. No matter how good the business is, it is better to test it yourself.

Cover the diaper in a prepared warm water container and cover it with a transparent glass. If there is water vapor, it proves that the diaper has good air permeability, because the diaper with good air permeability has an advanced microporous bottom film.


5. Water absorption

Water absorption is the "natal" ability of diapers, and the best way is of course to test it with water.

Lay the diaper flat and pour 300ml of salt water. The liquid of the diaper with good water absorption will quickly and evenly spread to the surroundings for faster absorption and more uniform diversion. Because a good diaper core will better conduct flow, make the liquid evenly distributed, and will not cause reverse osmosis.

6. Urine is obvious

While testing the water absorption of the diaper, check whether the urine display of the diaper is displayed in time. The urine display of the diaper can better let moms and dads understand the real-time situation of the baby's ass, so that moms and dads can better pay attention to the baby while busying themselves.

7. Reverse osmosis

Immediately after the water absorption test in the previous step, immediately press a dry paper towel onto the diaper after water absorption. If the dry paper towel is not wet, it means that the diaper has good water absorption and does not reverse osmosis, which can bring the baby a better enjoyment.

The materials used to make diapers usually include non-woven fabrics, toilet paper, high-absorbent core layer (absorbent resin and fluff pulp), bottom film (PE film), elastic, adhesive tape (front + left and right), waist elastic band, etc. Although the current styles of diapers on the market are dazzling, but the basic structure is similar. Generally speaking, diapers can be specifically divided into four parts: surface covering layer, flow guiding layer, absorbent core layer and bottom layer from top to bottom, of which the absorbent core layer is the most important component.

Diaper structure

It can be seen that an important guarantee for the quality of diapers is the production of raw non-woven fabrics. The quality of the non-woven fabric determines the comfort and dryness of the diaper. There are three main indicators: absorption speed, back seepage amount and side leakage. Among them, the absorption speed and the amount of re-permeation mainly depend on the "absorbent core layer", and the anti-side leakage ability depends on the design of the "flow guide layer" of the diaper. Therefore, the core layer and the diversion layer have become the key link for the achievement of excellent diapers.

1. The absorbent core determines the water absorption of the diaper. It is composed of two important raw materials: Super Absorbent Polymer (SAP) and Fluff Pulp.

2. The flow guide layer is a special non-woven material placed between the surface layer and the absorbent core layer. It can effectively help the liquid to be quickly transmitted from the surface layer coating material inward and diffuse longitudinally, so that the liquid is very It leaves the user’s skin quickly and is evenly absorbed by the core layer, preventing the diapers from being locally thickened due to concentrated liquid absorption and hindering subsequent urine absorption by SAP.

3.Non-woven fabric is the part covering the outer surface of the absorbent core. Traditional fabrics are woven from natural fibers such as silk, cotton and wool, while non-woven fabrics are usually made of plastic resin, such as nylon, polyester, acrylic, etc. The fibers or filaments are oriented or randomly arranged to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods. Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, light weight, etc., which is especially suitable for the production of absorbent sanitary products.
